[Penile angioscintigraphy in the study of vasculogenic impotence]

The development of diagnostical methods and evolution of multidisciplinary diagnostical approach contributed to frequent detection of vasculogenic impotence. The article deals with penile and iliac angioscintigraphy in order to determine the role of the vascular component in the onset of impotence. The investigation concerned 20 patients with marked impotence and a control group of healthy individuals. The vascular role of these disorders was determined according to Thouvenot, 1984 i. e. on the basic of the late penile perfusion represented by a deviated curve with maximum delay in comparison to the iliac curve. Vasculogenic impotence was found in 18 patients and non-vasculogenic in 2 subjects. Normal results were found in the control group. Angioscintigraphis results were compared with those of Doppler sonography and arteriography of the penile arteries. Contrary to the findings established by ultrasound method, radionuclide findings were not coordinated. The high agreement between angioscintigraphic and arteriographic findings in relation to the penile and iliac regions suggested the need of further clinical radionucleide studies in order to examine the possibility of its routine use in the selection or patients for invasive procedures in the diagnosis of vasculogenic impotence and the control of vascular surgical results.
